===Zinc-nickel plating===

Zinc-nickel plating is one of the best corrosion resistant finishes available offering over 5 times the protection of conventional zinc plating and up to 1,500 hours of neutral salt spray test performance. This plating is a combination of a high-nickel zinc-nickel alloy (10–15% nickel) and some variation of chromate. The most common mixed chromates include hexavalent iridescent, trivalent or black trivalent chromate. Used to protect steel, cast iron, brass, copper, and other materials, this acidic plating is an environmentally safe option.<ref>{{cite web|url=http://www.gattoplaters.com/zinc-nickel-plating.html|title=Zinc Nickel Plating - Zinc Nickel Electroplating - Gatto Industrial Platers, Inc.|first=Gatto Industrial Platers|last=Inc.|website=www.gattoplaters.com|url-status=live|archive-url=https://web.archive.org/web/20160207134253/http://www.gattoplaters.com/zinc-nickel-plating.html|archive-date=2016-02-07}}</ref> Hexavalent chromate has been classified as a human carcinogen by the EPA and OSHA.<ref>{{cite web|url=https://www.epa.gov/haps/health-effects-notebook-hazardous-air-pollutants|title=Health Effects Notebook for Hazardous Air Pollutants|website=EPA.gov|date=25 April 2016|access-date=2020-03-03}}</ref><ref>{{cite web|url=https://www.osha.gov/dts/chemicalsampling/data/CH_228697.html|title=Chemical Sampling Information - Chromium (VI) (Hexavalent Chromium) - Occupational Safety and Health Administration|website=www.osha.gov|url-status=live|archive-url=https://web.archive.org/web/20160305072102/https://www.osha.gov/dts/chemicalsampling/data/CH_228697.html|archive-date=2016-03-05}}</ref>
